Casual dining chains like Buffalo Wild Wings and Applebee's

Brands such as Buffalo Wild Wings, Ruby Tuesday, and Applebee's have faced sales slumps and dozens of restaurant closings as casual-dining chains have struggled to attract customers and increase sales.

In August, Applebee's announced it would close up to 135 restaurants, in part because it focused too much on winning over millennials and forgot its "Middle America roots."

"Millennial consumers are more attracted than their elders to cooking at home, ordering delivery from restaurants, and eating quickly, in fast-casual or quick-serve restaurants," Buffalo Wild Wings CEO Sally Smith wrote in a letter to shareholders earlier this year.

Contrary to popular belief, millennials are interested in purchasing homes. They're just waiting longer to buy.

A September report from the real-estate website and app Zillow found that millennials — i.e., people between the ages of 18 and 34 — are the largest group of homebuyers in the US. (The median age of a homebuyer is 36.)

"As a result of limited starter-home inventory, they're renting longer. And when they buy their first home, they're buying a much nicer home than a prior generation," he said.

"I mean, many people are basically skipping starter homes; they're renting until their 30s, and that first house they buy is a million dollars, and they just are not even buying the $200,000, $300,000, $400,000 home, which is a total mind shift as compared with previous generations. So they're still buying homes — they're just buying them later and buying them bigger."

Beer

In late July, Goldman Sachs downgraded both Boston Beer Company and Constellation Brands based on data suggesting that younger consumers prefer wine and spirits to beer, as well as the fact that they're drinking less alcohol than older generations more generally.

Beer penetration fell 1% from 2016 to 2017 in the US market, while both wine and spirits were unmoved, according to Nielsen ratings.

Napkins

The Post points to a survey conducted by Mintel, which highlights that only 56% of shoppers said they bought napkins in the past six months. At the same time, 86% surveyed said they had purchased paper towels.

Paper towels are more functional than napkins and can be used for more purposes. And the Post noted that millennials are more likely to eat meals out of the home, contributing to the decline.

Golf

"From the golf industry statistics, we know that rounds are down," Matt Powell of the industry-research firm NPD said in a video in 2016. "We know that millennials are not picking up the game, and boomers are aging out. The game is in decline."

While millennials have created new fitness crazes, like SoulCycle and barre classes, golf has failed to capture their interest in the same manner.

Motorcycles

"Our data suggests the younger Gen Y population is adopting motorcycling at a far lower rate than prior generations," AB analyst David Beckel said in a July note downgrading its rating of Harley-Davidson shares from "outperform" to "market perform."

Homeownership

"We believe the delay in homeownership is due to tighter credit standard and lifestyle changes, including delayed marriage and children," Michelle Meyer, a US economist at BAML, wrote in a recent note.

"We do not expect these factors to change in the medium term, keeping the homeownership rate low for young adults."

The decline in light yogurt can be traced to a growing demand for natural, protein-rich foods that fill up health-conscious consumers, instead of simply low-calorie and low-fat options. That's been a huge help for Greek yogurt, which appeals to customers seeking a filling option packed with protein.

On the flip side of the rise of protein and organic options is the fall of sugar.

Low fat-diets were the norm in the US in the 1980s and '90s. As food makers worked to cut fat from products, they began replacing it with another ingredient: sugar. As a result, "light" yogurts were often packed with sugar yet advertised as low-fat, healthy choices.

Bar soap sales fell 2.2% from 2014 to 2015, a time when the rest of the shower-and-bath category grew, according to Mintel.

And, millennials are to blame.

"Almost half (48%) of all US consumers believe bar soaps are covered in germs after use, a feeling that is particularly strong among consumers aged 18-24 (60%), as opposed to just 31% of older consumers aged 65-plus," Mintel wrote in a press release.

Banks

"There's a massive shift in consumer behavior and consumer trust," Rick Yang, a partner at the venture-capital firm New Enterprise Associates, told Business Insider. "I think coming out of [the financial crisis], millennials have a massive distrust of existing financial services."

While banks themselves will probably never die, bank branches and physical bank locations may soon be a thing of the past.

Nearly three-quarters of millennials with a bank account visit a branch once or less a month, according to BI Intelligence data. And slightly less than 40% of millennials do not visit physical banks at all.

Part of the reason is that when millennials do spend money, they're spending more on experiences like restaurants and traveling. Millennials are less drawn to aspirational, designer brands, and they're perfectly happy saving money by buying private-label lines, which further hurts traditional department stores.

Designer handbags

Brands like Michael Kors and Kate Spade have been forced to sell handbags at major discounts as millennials lose interest (and lack the money to spend on the bags). In some ways, the brands' mega-popularity contributed to their downfall.

Widespread popularity is the "kiss of death for trendy fashion brands, particularly those positioned in the up-market younger consumer sectors," industry expert Robin Lewis wrote on his blog.

While people have been investing more in their homes, some experts have questioned whether millennials' reluctance to buy homes could ultimately hurt these retailers.

"Millennials are redefining the American family," Jeff Fromm wrote in Forbes. "Millennials are delaying marriage and childbirth at rates never seen before. This cultural shift will have a near-term impact on housing: millennials may not need the same space, permanence, and practicality that most Americans want out of their housing."

Oil

McKinsey found that 14% of millennials say they would not want to work in the oil and gas industry because of its negative image — the highest percentage of any industry. And a recent survey by EY found that millennials "question the longevity of the industry ... Further, they primarily see the industry's careers as unstable, blue-collar, difficult, dangerous and harmful to society."

Teens are even more critical, with two out of three saying the oil and gas industry causes problems instead of solving them.
